Uphuhlisa njani usetyenziso lwe-Android

Ukuba ufuna ukuphuhlisa i-app yakho ye-Android, kukho izinto ekufuneka uzazi. Ezi ziquka iJava, Ukuqina komntu ngamnye, kunye neShareActionProvider. Funda ukuze ufunde ngakumbi malunga nabo kwaye uqalise. Xa sele ubabambe, uya kukwazi ukwenza i-app eyeyakho.

Java

Ukwenza i-app ye-Android ayifuni ulwazi lwekhowudi, kodwa inkqubo kufuneka yenziwe ngokufanelekileyo. Ukuba awuqhelananga neJava, ungasebenzisa i-app-bakasten, isixhobo sokwakha usetyenziso lwe-intanethi. Esi sixhobo sikuvumela ukuba uyile ngokukhawuleza i-app ngaphandle kolwazi lwekhowudi. Unokwenza ngokwezifiso ujongano lwayo kwaye wongeze umxholo, njengeevidiyo okanye iimephu. I-app-bakasten ilula kakhulu ukuyisebenzisa kwaye isebenziseka kakhulu.

Ngelixa iJava lulwimi olunamandla, ayisiyiyo eyona nto ilungileyo yokwakha ii-apps ze-Android. I-Kotlin ifikeleleka ngakumbi kwaye kulula ukuyifunda kuneJava. Ikwakhawuleza kwaye ikhuseleke ngakumbi. Nokuba uphuhlisa usetyenziso lwe-Android okanye amanye amaqonga, kubalulekile ukusebenzisa ulwimi ekulula ukuluqonda.

Ukuba ungumqali, luluvo oluhle ukuqala ngokufunda incwadi yeJava. Abaphuhlisi be-Android bayakwazi ukusebenzisa indawo yeprogram ebizwa ngokuba yi-Android Studio ukuphuhlisa usetyenziso lwabo. Isixhobo somphuhlisi we-Android sinika izifundo ezininzi kunye nemizekelo. Ikwabonelela ngeforum yeCHIP, apho unokuthetha nabadwelisi abanamava kwaye ubuze imibuzo.

Ungasebenzisa kwakhona umzekelo wedatha ekhuphekayo ukuze uqalise. Oku kuya kukunceda ukuphuhlisa apps Android ngokukhawuleza. Umzekelo, ukuba wakha imboniselo yoluhlu, uzakufuna iklasi ebizwa ngokuba yiArrayAdapter edibanisa idatha kuluhlu lokujonga ubeko. Ngaphezu koko, Uya kudinga ilayibrari yeJava ebizwa ngokuba yiGSON. Oku kuya kumephu izinto zeJava kwizinto ze-JSON ngokuzenzekelayo.

ShareActionProvider

Ukuba ufuna ukwabelana ngomxholo nabasebenzisi bakho, kufuneka usebenzise iklasi ye-ShareActionProvider kwi-Android. Le klasi inoxanduva lokudala nokubonisa iimbono zokwabelana. Unokongeza lo mboneleli wesenzo kwimenyu yoKhetho. Iza kubonakala njengophawu lokuya-kwinqaku kwi-Action Bar, kwaye iya kubonisa imenyu eyehlayo kunye ne-ShareApps.

I-ShareActionProvider yenziwe xa usebenzisa i-Share-Menueintrag. Le klasi yenza kube lula ukwabelana ngomxholo kunye nezinye ii-apps ze-Android. Isebenzisa iThala leeNcwadi leNkxaso ye-Android ukubonelela ngesenzo. Xa umsebenzisi ecofa i icon, iya kuthumela imixholo ye-app kumntu wesithathu. Emva kokuba le nkqubo igqityiwe, intshukumo enxulumene nesabelo iya kugqitywa, kwaye usetyenziso lwe-Android luya kubuyela kwimeko yalo yokuqala.

I-ShareActionProvider iya kubonisa i-icon yokwabelana kwi-ActionBar. Xa umsebenzisi ecofa i icon yokwabelana, imboniselo iya kuvela. Ungakwazi nokuseta injongo yomsebenzi wokwabelana ngokongeza umyalezo kwi-ActionBar. Le ndlela, umsebenzisi wakho angabelana ngokulula naluphi na ulwazi.

I-Android liqonga elikhulu lokwakha usetyenziso, kwaye ukuphuhlisa enye kulula kakhulu. Qalisa ngokufunda kwi-ShareActionProvider kunye neeNkqubo zeNjongo. Le ndlela, ungaphuhlisa usetyenziso lwakho ngokukhawuleza kwaye wonwabe ngakumbi.

XML disk chain

Ukuba ufuna ukwakha i-app ye-Android ngaphandle kwenkqubo, ungasebenzisa umakhi we-app. Aba bakhi be-app ye-intanethi bakunika i-interface ekulula ukuyisebenzisa ekuvumela ukuba utsale kwaye ulahle izinto ukwenza i-app oyifunayo.. Unokongeza iividiyo, iimephu, kunye neminye imixholo, kwaye wenze ngokwezifiso ujongano lweapp njengoko ufuna. Uninzi lwabakhi be-app bayazichaza, kwaye inkqubo iyakhawuleza kwaye ayibuhlungu.

Ukuqina komntu ngamnye

Ukuba ufuna ukwenza usetyenziso lwe-Android, Kuya kufuneka ukwazi ukwenza inkqubo kwiJava. Kukho iintlobo ngeentlobo zezixhobo zokwakha ze-app ezikhoyo ukukunceda wenze usetyenziso lwesixhobo sakho se-Android. Nje ukuba ufumene eyona ilungileyo, ungaqalisa inkqubo ngoko nangoko.

Ukwakhiwa kwe-app ye-Android akunzima njengoko unokucinga. Unokufunda indlela yokucwangcisa usetyenziso olulula ngokucofa okumbalwa kwemouse. I-Android App Programmieren Kurs yikhosi yenqanaba lokungena elungiselelwe abadwelisi kunye nabaqalayo. Ineemfuno zekhosi ephantsi kwaye ifuna ulwazi olusisiseko kuphela ngolwimi lokuprograma lwe-Android. Uya kuba nakho ukwakha i-app yakho usebenzisa izixhobo zokutsala kunye nokulahla ukwenza inkangeleko entle, ujongano olusebenziseka lula.

I-intanethi ye-Android Apps Programmieren Online-Kurs sisixhobo esihle kakhulu sokufunda uphuhliso lwe-Android app. Inkqubo ibandakanya 35 izifundo, ngasinye sazisa ngomxholo osisiseko.
